Tech Talk, Faculty of Engineering, HKU


Dear friends, colleagues and students,

We are delighted to announce that the Tech Talk will be held at the Tam Wing Fan Innovation Wing Two with details as follows:



Tech Talk is a series of forums and dialogues given by engineering researchers of diverse academic backgrounds to share their insights on innovation-related topics.


Topic: Innovation of Originality for Solving Sand Shortage Crisis around the World including Hong Kong (解決香港和世界缺砂危機的原創科研成果)


About the talk:

Sand is the most exploited raw solid material in the world and used for construction of buildings, roads, railways, bridges, tunnels and beaches. It is also used to make the glass and silicon chips. The annual consumption for use in glass, concrete and construction materials has reached 50 billion tones, which is extremely high. Consequently, according to United Nations’ reports, the world is facing a shortage crisis of sand, as one of the greatest sustainability challenges of the 21st century. Such sand shortage crisis around the world has affected the use of sand in Hong Kong since Hong Kong does not produce any sand and all the sand used in Hong Kong is imported from Mainland China. In this Teck Talk, Professor Yue will present his technological innovation of originality. His innovation can solve this global sand shortage crisis. More importantly, his innovation can provide a stable supply of quality sand for construction and industry and offer new raw material resources for developing new industry in Hong Kong. Professor Yue has discovered that the local ordinary soil in Hong Kong can be converted into the materials of sand and clay. The sand is siliceous sand and mainly quartz mineral. The clay is mainly kaolinite mineral. Both materials can be used as the raw solid materials in construction and other industry. Professor Yue will demonstrate that his technical innovation is simple, environmental-friendly, sustainable and cost-effective and can be applied to many places around the world for producing quality sand materials.
